IMPROVEMENT IN WATER-ELEVATORS.

The Schedule referred to in these Letters Patent and making part of thesame To all whom it may concern Like letters refer to like parts in thedifferent viewsk presented.

The nature of this invention relates to a device for tipping the bucketof a water-drawer by lmeans of a roller attached to a vibrating arm,herein more .fully described; also, a device whereby the speed of thedescent ot' the bucket into the well is governed.

In rig. 1, A-represents the curb or case of themachine, in the' top ofwhich isjournalled a grooved wheel, l5.

On the shaft 0,1ig. 2, close to said wheel, is a ratchetwheel, D, iig.4, to the side. of which is attached a Pivoted to the standardV F is athe ratchetwheel referred 4to.

To said standard is also pivoted a lever or brake, H, from the side ofwhich projectsV a pin, a, g. 4, under which the lower end of the pawlproceeds, and is operated thereby, as and for a purpose hereafter shown.

I is the bucket attached to the rope J by the bail K.

immediately around the inside of the -rim of said bucket is a rib, L,fig. 3, whereby is formed as'houlder, b, the purpose of' whichwill'presently be shown.

.M is a tilting-bar, from the centre of which projects'a ste-m, N, onwhich is secured a roller, O, the purposeof which is as follows:

1n this class of machines, for drawing water, it is necessary to use aiiat chain for raising the bucket, in order that it may present theproper side to the tipping-device, for should a rope or `common chain beused, the bucket would swing around, and as often present the sides towhich the bail is attached to the tipping-device as the proper sides.

In order to avoid this difiiculty, yso that a rope can pawl, G, toengage be used instead of a liat chain or other kind, resort is had to adevice for turning the bucket, so as to presentit properly to the tilt.

Such devices are not only expensive, but in consequenceV of the? 'workthat they have to perform, they are unavoidably complicated, andtherefore liable t0 become deranged, and hence inoperative.

To avoid this ditculty is the purpose of the roller O, referred to,which, when the bucket ascends, and presents the bail-side more or lessto the roller, is .-a'ught thereby, and -will roll upon the edge of the'bucket, turning it around till-the pivotal linie 0f the bail arrivestransversely in the case, as shown in iig.

1, in proper position for tilting, which it willdo as the.A

bucket is continued to be drawn upward.

To prevent the bucket frombecoming disengaged from the roller, whilethus being tilted for 'discharging the Water, is the purpose of the ribL, referred to, which, asI the bottom of 'the bucket is elevated, cannotslip therefrom, as the thick end of the rollerl is caught by the'shoulder b, and is thereby retained during the discharging of theWater.

It will be obvious that by this device an ordinary chain or rope can beused for drawing up the bucket, thereby dispensing with the use of aflat chain, which is not only expensive, but very liable to break, inc0n- ,sequence of its peculiar construction.

In this class ofwater-drawers, a tilting-device is generally used, andif a common chain or rope is employed for drawing up the bucket, anadditional device is introduced for bringing the bucket to the right'lpositionfor tilting.

" By the use:4 of the roller referred to, the tilter is made to d0 thisoffice of guiding the bucket, so that it can be tipped, thus performinga twofold work', thereby dispensing with the expensive arrangement ordevice for guiding the bucket, above mentioned.

As the bucket is lowered into the well, it is re- 'strained fromdescending too fast, by the brakeH,

which, on depressing the outer end of the arn H', 'the inner arm H isbrought in contact with the wheel E, thereby controlling its revolutionaccording to the pressure applied.

At the instant the external arm H is depressed,

the pawl G is disengaged from the ratchet by said arm pushing downwardthe lower end of the pawl by means of the pin a.. Thus a disengagementof the pawl is madesimultaneously with the application of .the brake,and, per contra, on the disengagement of the brake with the wheel, thepawl falls immediately upon the ratchet.

By this simple arrangement'of the pawl and brake,

no especial care is required in order .to retain the.

bucket at any particular elevation in the well, as

,the action of the pawl is consequent upon the action of the brake, andnot dependent upon' the attention and care of those drawing water.

What I claim as my improvement, and desire t0 secure by Letters Patent,'is- 1. The tilting-bar M and roller O, in combination with the rib Land shoulder b around the inner edge of the bucket, in the manner as andfor the purpose set forth.

2. The roller 0, in combination vwith. the bucket I,

arranged and operating in relation to each other, in

the manner and for the purpose substantially as ,set forth.

3. The combination of the pawl and wheel G D, brake H, pin a, andwh'eelrE, arranged to operate conjointly in the manner as and for'thepurpose specilied.
